Electronic Liquid Level Sensor

Description

Electronic Liquid Level Sensor The sensor detects liquids by proximity, with an accuracy of approximately +/- 1 cm. The sensor operates at 5 VDC and is powered by the controller board. The controller operates with a voltage between 12 V and 25 V DC or AC. The relay output is normally connected between terminals C and 1, and switches to C and 2 when activated. Relay rating: 1 A at 124 VAC / 2 A at 24 VAC Set – Sensor and controller board. Connections – Power supply, sensor connection, and relay contact. Note: This sensor can be adapted for other applications. It must be installed in a non-metallic tube (e.g., as shown in Figure 3). New Material
